SPECIFICATION forming part of Letters Patent No. 400,565, dated April 2,1889.

Application filed January-l1, 1889- Serial No. 296,072. (No model.)

9,.formed with a catch-tooth, 16, which en- .70 (L whom, it 72mgconcern.-

Be it known that we, WILLIAM A. HANEY and ENOGH G. I-IANEY, both ofMedia, in the county of Douglas and State of Kansas, have invented a newand Improved Brake-Operati'ng Attachment, of which the following is afull, clear, and exact description.

Our invention relates to a brake-operating mechanism, theobject of theinvention being to provide for an enlarged range of movement for thebrake-shoe, but to provide for the application of. the power to thegreatest advantage at the time when the brake-shoe is brought againstthe peripheral face of the wheel.

To the end'named the invention consists, essentially, of a lever and aslide mounted thereon and pivotally connected to a link, theconnecting-rod, which extends to the brakeshoe, being connected to theslide, all as will be hereinafter more fully explained, and specificallypointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures and letters of referenceindicate corresponding parts in all the views. I

Figure 1 is a side view of our improved brake-operating mechanism, theparts being shown in full lines as they appear when the brake isapplied,and in dotted lines at a as they appear when the brake isreleased, and also in dottedlines at b as the parts appear when thebrake is moved to a position such that it will be out of the range ofthe mud thrown by the wheel. Fig. 2 is a plan view in partial section,and Fig. 3 is a cross-sectional view of the attachment.

In the drawings, 10 represents a rack, which is arranged so that it maybe connected to a wagon-body, so as to be held at some distancetherefrom. In the specific construction shown in the drawings the rackis made integral with a bent arm, 11, to which arm there is pivotallyconnected a lever, 12, and a link, 13. The rack 10 and arm 11 are inparallel planes, the arm being bolted directly to the wagon side, whilethe rack rests in a plane at some distance therefrom, the extending endof the rack being supported by a sleeve, 14, through which aconnecting-bolt, 15, is passed.

To the lever 12 there is connectedafender,

gages the teeth 0 of the rack 10, and to the lower end of the leverthere is connected a spring, 17, that bears against the inner side faceof the rack, the upper end of this spring being guided by fingers 18,which are rigidly connected to the fender 9, the action of the springbeing to hold the tooth 16 in engagement with the teeth 0; but when itis desired to free the lever-tooth from engagement with the rack-teeth,the lever is inoved slightly in the direction of the arrow shown inconnection therewith in Fig. 3, after which the lever may be moved inthe direction of the arrow shown in Fig. 1, and in order to prevent toogreat a movement in the direction of the arrow shown in Fig. 3 weprovide the lever with an arm, 19, which overlaps the rack 10, said armbeing connected to the fender 9, as shown in Fig. 3.

Upon the lever 12 there is mounted aslide, 20, to which the link 13ispivotally connected, and to'this slide 20 there is also pivotallyconnected a rod, 21, the opposite end of said rod being arranged forconnection with the brake, as will be readily understood. The slide isslotted, as shown, so as to ride freely over the fender.

In practice we prefer to arrange the teeth 'of the rack 10 as shown inthe drawings-that is,'to provide teeth only at the forward portion ofthe rack, the rear portion of the rack being simply grooved to admit ofthe passage of the tooth 16.

In operation, as the lever 12 is moved forward from the positionindicated by the dotted lines at a to the position in which the partsare shown in full lines in Fig. 1, the slide 20 is carried downwardtoward the fulcrum of the lever 12, and hence the effect of the powerapplied to said lever is increased as the lever is pushed forward, themotion of the rod 21 correspondingly decreasing. As the lever, however,is freed from engagement with the teeth c -and moved in the direction ofthe arrow shown in Fig. 1, the movement of the rod 21 increases as thelever is moved, as just described. To simply release the brake, thelever 12 would be moved to the position shown by dotted lines ,at a; butif it were desired to throw the brake clear from the wheel, so as toprevent it from collecting mud, the lever would be moved to the positionindicated by the dotted lines at Z).

From the construction hereinbefore de scribed it- Will be seen that whenthe lever is adjusted to the position shown either at a or b in Fig. 1the fender 9 will bear against the edges of the rack 10, the spring 17at this time holding said fender firmly against the rack and in anyposition to which it may be adjusted, the groove formed in the rackbeyond the teeth 0 being of such depth that the tooth 16 will ridefreely therein.

Having thus described our invention, We claim as new and desire tosecure by Letters Patent- 1. In a brake operating attachment, thecombination, With a rack, of a toothed lever, a slide mounted upon thelever, a pivotallymounted link that is pivotally connected to the slide,and a rod pivotally connected to the slide and arranged for connectionwith a brake, substantially as described.

2. In a brake-operating attachment, the combination, with a rack theteeth of which are formed only at the forward edge, of a toothed leverarranged to engage the rack, a spring carried by the lever and arrangedto bear upon the rear face of the rack-bar, a slide carried by thelever, a pivotally-mounted link that is pivotally connected to theslide, and a rod pivotally connected to the slide and arranged forconnection with a brake, substantially as described.
